There are a few things to keep in mind. While the shirt is made from a blend of polyester and spandex, its breathability might not match that of more natural fiber options, which could be a concern for some users. Additionally, the care instructions advise machine washing, but frequent washing might affect the longevity of the moisture-wicking properties over time.
